I met these people while heading up the North Fork of Lone Pine Creek trail. They were making that trail entrance more open and obvious, and did a good job of it (I noticed on the way down). That part of the Mountaineers' Route and a supposedly un-maintained trail.
One of the two rangers with them checked my permit.
